CONVEYER O'R ELEVATOR.

' Application inea August 1s, `192s. serial No. 658,172.

To all whom t may concern:

Be it known that I, PETER M. YOUNG, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful -Conveyer or Elevator, of which the following is a specification.

'Ihis invention relates to an article conveyer or elevator, such as used in markets, groceries, or other stores, for handling articles, such as packages or bundles. ,Such apparatus usually operatesto receive the articles on one level and raises them to a The gen-- delivery point at a higher level. eral object of the inventionis to prov1de an article conveyer or elevator to which the articles may be fed automatically, an'd which will operate effectively to take the articles from the loading point and deliver them at a delivery point at a higher level. One of the objects of the invention is to provide a 'construction at the loading point which will operate to insure that the different carriers or holders on theelevator will not be overloaded, and operating incidentally to hold back for the next carrier, the other articles or packages which may have accumulated at the loading point. y,

.One ofthe objectsof the invention vis to provide an apparatus of this general type which is capable of handling bundles of any size, that is tosay, bundleshaving a wide range in size. I ainaware that in elevator apparatus a loading platform may be con structed of slats which project into the path of `carriers on an elevator, the said carriers being in the form of bars which project outwardly from the belt or endless chain and pass upwardly throughgthe spaces between theslats of the loading platform. Such construction maybe well adapted for handling large' articles such as boxes or the like, but necessarilyv involves the presence of slots or openings in the loading platform; suchv Slots render the apparatus illadapted for use with small articles. Furthermore, it is diliicult to obtain a nice alinement between the parallel bars which form the carrier, and the slots; and of course, if one of these bars should be out of'line with its slot it would strikethe adjacent slot of the platform and cause a breakage to occur. My invention overcomes the disadvantages of a loadingapparatus of such a construction, and enables packages ranging greatly in size to be effectively handled.

' It isV frequently necessary to provide for delivering the elevated articles onto another substantially horizontal conveyer atV an up er flo-or or elevated point, and one of the objects of this invention is to provide simple means for accomplishing` this.

In the operation of the elevator the articles may come to it in a closely crowded condition, and it may happen thatin loading the articles onto the holders van article might fall by accident past the holder uponk which. it should be loaded.' One of the objects of this invention is to provide means for insuring thatsuch an `article will be picked up by an article carrier or holder following the 'one upon which the article should have been loaded.

Further objectsl of the invention will ap. pear hereinafter. a

The invention consists in the novel parts and combination of parts to be described hereinafter, all of which contribute to produce an efficient article conveyer or elevator.

A preferred embodiment of the invention is described in thefollowing specification while the broad scope of the invention is poin'teclout in the appended claims.

In the drawing:

Figure 1 is a vertical section through an article conveyer or elevator embodying my invention, .certain parts being broken away.

Figure`2 is a plan and partial sectionv on In practice it is contemplated that the elevator-will serve a plurality Vof counters on a floor, and for this` purpose I provide a substantially horizontal conveyer belt l upon which a salesman or clerk at any counter may deposit the wrapped articles or packages that are to be delivered. At the delivery end of this conveyer 1, which passes around a suitable roller 2, I provide a loading platform 3 which supports the articles, and this loading platform is constructed so that it projects into the path of a plurality of carries or holders 4 carried on an endless .exible conveyer 5. As these holders 4 pass which, if desired, may be disposed in a ver-4 tical position as shown, the lower end of the same passing around a lower roller 8,

and the upper end passing around an upper Y.

` it will it up.

It is understood that the embodiment of then invention described herein is only one of the many embodiments this invention may take and I do not Wish to be limited in the practice of my invention nor in my claims to the forth. What l claim` is: 1. In an article carrier or elevator, the

combination of an endless co-nveyer having holders attached thereto and movable past a loading point, a loading platform fo'r supporting the articles and having a plate projecting into the path of the holders, saidV loading platform lbeing movably mounted and having means other than the said plate engaged by each holder as it passes the loading oint and cooperating with the holder to displace the loading platform from the path of the holder and deliver the article from' the loading platform to the holder.

' 2. In an article carrier or elevator, the

combination of an endlessl conveyer having holders attached thereto and movable past a loading point, a loading platform for'sulpporting the articlesandirojeeting into t e path of the holders, sai

of enabling the loading platform to move into a retracted position out of the path of v:iii

the holders, and'means associated 'with the loadingplatform and cooperating with the holders to displace 'the' loading platform from the path of the holdersl and transfer the article on the loading'platform toI each holder as it pass the loading point.

.3. 'In an article/ 'carrier or elevator, the

combination of an! endless conveyer hav-ing holders attached thereto and movable vpast a loadingpoint, a loadingplatform for s'up porting the articles and projecting into the ath of the holders,said loading platform aving a transverse joint enablin the platform to move out of the path o th'e holders,'an inclined cam'member pivotall' attached to the' outer end of the -plat orm,

projecting into the path of the holders andV cooperating with each holder 'to displace the loadingplatform from the path lof the holder and simultaneously transfer the ar- Y ticlefrom lit to the holder.

4. In an articlecarrier or elevator, the.

combination of an endless conveyer having pick up the lost bundle and'carry,

particular embodiment set loading plat-orm`, having a joint extending transversely thereholders attached thereto and movable past a loading point, a loading platform forl sup-porting the articles and projecting into outer plate supported by the lower of said v joints, said outer plate lying in the path of lthe holders and held in an inclined .position so that lan article upon it will rest against the face of the endless conveyor, and means carried by the said outer plate, lying'in thev path of the holders, and cooperating with each holder to displace the loading platform vfrom the path of the holders and transfer an article 'upon'it to the holder as it passes the loading point.

5. In yan article carrier or elevator, the combination of an endless belt, rollers around which the ends of the beltpa-ss, a sprocket Wheel rigid with each roller, an endless sprocket chain lying substantially in the plane of the belt, passing around' the sprocket Wheels for rotat-ingtlie rollers and effecting an advance ofy the endless belt, article holders attached at' their inner ends to the endless chains, .and projecting outwardly from the belt, a 'second conveyer comprising abelt disposed in a plane transverse to the plane of movement of the first named belt andwith its edge disposed ad-i jacent to tlie face of the'rs't named belt .and
